RIGIMILL BENEFITS OF THE RIGIMILL

Transcription

1 BENEFITS OF THE The RigiMill was developed together with SECO tools to be the machine that can handle the fastest chip removal rate in the world for both titanium and aluminum Right-sized gantry for aluminum milling and titanium milling Generally 40% faster per part than on a 4-spindle machine No need for operator to load part on machine table No need for manual chip handling Foundation cost less than 70% of multi-spindle machines Normally 2/3 of the cost of a multi-spindle machine Up to 970 cubic inches chip removal in aluminum Up to 55 cubic inches chip removal in titanium Robotic tool loading this design maximizes spindle production time because the robot will measure and verify the tools before they are put in the spindle New design, competitors have design from middle of the 80 s One specific gantry for aluminum machining and one for titanium machining All parts FEM analyzed Modig can show proof of machine stiffness Outstanding performance award from Boeing only machine tool builder outside U.S. to receive this award Double chip conveyor for best chip removal Small footprint and minimized height to achieve the best stiffness

2 GENERAL INFORMATION Name RigiMill Design Year 2015 Axis Gantry Type Feeds and Speeds Acceleration During Machining Spindle RPM Power and Torque Tool Taper Materials 3-, 4-, or 5-axis options One specific gantry for aluminum milling and one specific gantry for heavy machining in steel or titanium. 1,200 3,200 depending on gantry 0.3 1G depending on gantry Fischer motor spindle for aluminum, gear driven spindles for TI From 200 RPM in titanium and up to 33,000 in aluminum From kw in aluminum and 500-2,500 Nm for titanium and steel HSK 63A, 100A or 125A depending on material Titanium, steel, aluminum or composite Working Envelope X = unlimited, Y = 61,4, Z = 35,4 Chip Removal Rate Advantages 970 cubic inches in aluminum and 55 cubic inches in titanium World s first 2 in 1 machine (roughing and finishing in the same machine) Pallet system up to 600 PRICE compared to multi spindle machines Customized solution dedicated for customers parts Wide variety of solutions for automation Robot tool loading with tool magazine holding up to 300 tools Flat floor design Extremely small footprint Capacity per square foot higher than competitors Generally 40 50% faster than 4-spindle machines per part Less extensive and thus less expensive foundation required Good price level for smaller companies Cooperation with SECO tools for best customer solution

3 GENERAL TECHNICAL INFORMATION Focus on parts that are 80 and longer, otherwise we will have competition from commodity machines PROCESS High speed 5-axis aluminum milling Roughing in titanium or steel with up to 9,000 pounds pressure on the tool Turn-milling OPTIONS Automatic pallet system for parts up to 600 long Robotic loading and unloading for parts up to 100 long Rotary tables T-slot table Rotating window fixtures Dual zone machining areas CNC fixtures for a variations of parts Composite vacuum extractor Vacuum clamping fixtures Briquette press for chips Ambient coolant level 100 bar thru spindle coolant NOTE: many features normally considered options (such as probes) are already standard on Modig machines

4 TECHNICAL ADVANTAGES Double AC motors in Y and Z axis Four AC motors in X axis for best speed and acceleration Five guideways in Z axis for best stiffness and accuracy Twelve carrier packs in Z axis for accuracy Eight carrier packs in X for superior stability Big AC 8 two-axis head that can handle the cutting forces from a 170kW spindle Mega torque motors in A and Z axis Heidenhain rotational scales in A and Z axis All moving parts made of cast iron for highest stiffness, (welded steel design is very poor) 4 rack and pinions on X-axis for zero backlash (two is totally inadequate for a machine like this) Double Heidenhain scales in all axis for highest accuracy Double ground ballscrews with internal cooling in both Y and Z axis Fanuc robot tool loading for minimizing unproductive spindle time. Robot measures tool length and diameter in Renshaw probe instead of machine Up to 300 tool pots User friendly HMI operator control All roller guideways are 65 mm for highest stiffness (ball bearing guideways are very inaccurate) Size of rail and roller pack also important Fanuc 30i B system (the top of the range that Fanuc can provide) 3D crash protection software, for zero crashes (very important) not available from Siemens Spindle vibration monitoring Torque detection monitoring Spindle temperature monitoring 27 touch screen for operator with Modig s on HMI Renishaw NC4 tool measuring and RPM 60 touch probe standard Post processor from ICAM SECO provide cutting data and help at site for best time and results during machining 3R hydraulic fixing point for pallets for highest accuracy (extremely good) Pallets up to 16 meters in length Automatic pallet loader with two stations for loading parts outside working envelope Hydraulic clamps and vacuum to hold part in position No cleaning the part from chips after machining. Machine uses water curtain to clean the part before pallet is removed Ability to extend machine in the X-axis easily after installation Option to add a second gantry on the same machine after installation

5 INDUSTRIES SERVED: Aerospace Marine Transportation Heavy Industries Automotive EXCELS AT THESE PARTS: Spars Wing stringers Landing gear Titanium seat tracks Wing ribs Panels Titanium frames Aluminum frames Window frames Railroad tracks Rocket launcher parts Aircraft doors Large crankshafts Large connection rods Leading edge Flap tracks Landing gear beams Engine mounts The RigiMill will have most impact with longer parts which eliminates competition from commodity machines. Any part that fits within the working envelope shown below is ideal for the RigiMill.
